Is anyone out there doing any sort of study of "cultural commodification"
of Native religions, cultures, etc. by Westerners (I'd assume it's most
prevalent in capitalist countries?).

Can anthropologists, coming as we do from a discipline with a legacy
(hopefully on its way out) of white Westerners building careers as
"experts" on Native cultures, analyze cultural
commodification/appropriation using the tools of our trade?
